Pulp and Paper

Svartsjoana, Sweden is the end site of the species diverse and highly valuable Eman river. Svartsjoana, has served as the sedimentation basin for mercury laden pulp fibres coming from a nearby paper mill. Dredging of 260000m3 of Svartsjoana sedimentation began in 2006, being captured in Geotube® units with the addition of polymers.

SCA Tissues, Cherokee, Alabama, had issues with the screw press in its Wastewater treatment plant malfunctioning. With only 6 hours of retention time, the paper mill commissioned the use of a Geotube® container to hold the waste allowing the plant to continue running while a week of repairs began.

Stora Enso paper pulp mill uses a 2,000,000 gallon tank to hold its wastewater to allow for the settling out of alum solids. Annually this take needed to be drained. With an expected 60,000-80,000 pounds of solids in the tank, Geotube® technology was used to dewater this tank. A high success rate was achieved with over 99% of total solids captured.
